Explanation:

Bond Sam

6% / 2 = 3% semiannual payments 4 years to maturity = 8 payments present value = future value = 100

using an excel spreadsheet I calculated the new market value (present value) if interest increases by 2% ⇒ 4% semiannual, 7 cash flows of $3, one last cash flow of $103:

if interest increases by 2%, present value (market value) will decrease to $93.27 ⇒ 6.73% decrease

using an excel spreadsheet I calculated the new market value (present value) if interest decreases by 2% ⇒ 2% semiannual, 7 cash flows of $3, one last cash flow of $103.

If interest decreases by 2%, present value (market value) will increase to $107.33 ⇒ 7.33% increase

Bond Dave

6% / 2 = 3% semiannual payments 19 years to maturity = 38 payments present value = future value = 100

using an excel spreadsheet I calculated the new market value (present value) if interest increases by 2% ⇒ 4% semiannual, 37 cash flows of $3, one last cash flow of $103:

if interest increases by 2%, present value (market value) will decrease to $80.63 ⇒ 19.37% decrease

using an excel spreadsheet I calculated the new market value (present value) if interest decreases by 2% ⇒ 2% semiannual, 37 cash flows of $3, one last cash flow of $103.

If interest decreases by 2%, present value (market value) will increase to $126.44 ⇒ 26.44% increase
